    Thats a good point. I'll give you that. And you may have done alot more brake jobs then me but this forum is pretty whacky where people argue with you about changing the trans fluid at 30K but not about changing the brake fluid at 30K. Kinda silly because no matter how bad the brake fluid is it will still stop. And no matter how bad the fluid is it won't really harm anything unlike worn out cvt fluid which will get very expensive. So rubber debris in b fluid your way past caliper time. No big deal. Can't imagine how many miles has to be on a prius to see that though is my point.

    So color me confused about this forum.

    Mangoose works fine on Win 7. The M-VCI only works on XP - or at least, I couldn't get it to work on Win 7. I gave in an got a netbook when I only had the M-VCI.

    @ manza I am willing to loan out the M-VCI for folks that want to try it before buying and waiting for shipping from China. All I ask is funds to at least ship it to you and a return in a decent time frame.

    The reason for vehicle flushing recommendations is to get rid of absorbed moisture which reduces the boiling point of the brake fluid. High levels of moisture will also corrode iron and aluminum brake components. But water absorption is a function of the climate in which the vehicle is used. So testing should be the best approach.

    I think I'll do another flush at 60k and make a video with a go-pro for all of you.

    Oh man. So confused. I was digging in thoroughly to do this myself. My brake fluid DEFinitely needs to be flushed (154k miles....never flushed. Mostly living in dry climate but 1.5 yrs in Houston area, so definite moisture in it). Anyway, after watching several videos and feeling pretty confident that a simple flush, without using Techstream, would be fine, I'm starting to wonder.

    I was going to go ahead and get a VCI, but I don't even have a Windows computer....so that adds another layer of ridiculous to my preparing to do my own Techstream brake flush. (not to mention figuring out the software...and I know it might be handy as I go forward, but I've got a Scanguage for codes and such, and most other maintenance that's likely to be a DIY project for me isn't going to require techstream).

    Sp my questions for anyone with any answers and advice:

    a) Is the sequence: R rear / L front, then L rear / R front (because of the cross-connected lines allowing for failure of one side while retaining some balance of braking, if this were to happen, so flushing one cross-connected set of lines, then the other is best)?

    b) If car is in "invalid" mode, and I just use the onboard brake pump to flush the system, is it adequate?

    c) Any difference between DOT4 and DOT3 for our cars ?

    d) Is there a significant benefit to using the Techstream system because it flushes a lot better / does other things to the traction control system/ABS/etc ?

    I'm absolutely prepared to simply bite the bullet and have this done at the dealership but I've learned that taking things to the dealership often doesn't result in the best quality work being done, so I trust myself better. Nevertheless, with Mendel even saying he takes his to the dealership for this, I'm pretty open to having the brake flush done by them.

    Input and answers anyone may have are much appreciated!
